Automatic Functions and Unexpected Start-Ups
Unexpected start-ups during maintenance:
– Lock out and tag machine controls before
performing maintenance or repairs to
avoid unexpected start-up. Failure to
properly lock out the machine can lead to
injury or death. Someone may accidentally
start the machine from the control room or
an unexpected occurrence may activate a
control. For example, a power surge may
alter the logic of the control system status
causing an unexpected machine
movement or sequence.
Welding Equipment
Weld repairs are to be performed only by qualified
personnel. Welders and welder’s helpers must wear
protective clothing and equipment.
Precautions must be taken when torch cutting
and/or welding due to the health hazards posed by
many metals. Anyone performing these types of
procedures should avoid breathing the fumes. Such
procedures should be done outdoors or in a well
ventilated area with either a separate clean air
supply provided to the mechanic or with local
exhaust of fumes. Please refer to EU, OSHA,
MSHA, or other applicable standards as
appropriate. One of the most frequently used tools
around the Crushing Plant is the cutting torch.
Crushing Plants which are equipped with hydraulic
components and/or conveyor belts and/or v-belts
should have these components depressurized and
adequately covered with flame-proof material so
that sparks, weld spatter, etc., cannot reach theses
areas. Ruptured high pressure hydraulic lines will
quickly vaporize the hydraulic fluid as it reaches
WARNING
Machine parts may move unintentionally
and cause a risk of injury. Absence of safety
functions may cause dangerous machine
movements.
Do not tamper with limit switches or other
safety devices included in the system.
DANGER
If danger zones are not respected during
machine operation or maneuvers there is a
risk of serious injury or death.
Many devices operate automatically,
following certain sequences which have
been programmed into the logic system
(e.g., programmable logic controller,
microcontroller, relay system or similar). The
danger zone is any area within the confines
of moving machine elements, feed material
or beneath any objects being lifted. Do not
enter these danger zones unless the
machine has been properly safeguarded
according to the Crushing Plant lockout
procedure and manufacturer’s instructions.
